ROPE-CLAMP.

Specification of Letters Patent.

Patented Feb. 15, 1916.

Application/filed May.27, 1915. SerialNo. 30,797.

To all whom itmay concern:

Be it known that 1, Louis M. EVJEN, a' citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of the Bronx and State of New York, have invented anew and Improved Rope-Clamp, of which the following is a full, clear, and exact description.

This invention relates to rope clamps and has forits general objects to improveand simplify the construction and operation of" devices of this character so as to'be reliable and eflicient inuse, comparatively simple and inexpensive to manufacture, and so designed that a rope canbe tightly clamped without-danger of slipping, and at thesame time the rope is capable of being easilydisconnected.

Amore specific object ofthe invention is. the provision of a rope clamp comprising slidably c'onnectedmembers having rope-receiving slots which. are disposed=transversely to each otherso that by successively engaging the rope to be fastened in the slotsof the respective members and relatively sliding the same, the rope will be gripped firmly' so that it cannot slip, there being a wedging action by the insertion of the rope in the slots of the respective members, and this, in connection with the fact that the clamped part-of the rope'is disposed at an angle to the portion of the rope that receives a strain, effectively resists slipping of the rope in the clamp.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a plan view of the device with the rope clamped therein; Fig. 2 is a similar view before the rope is engaged by the initial clamping member; Fig. 3 is a side view of Fig. 1; Fig. 4 is a side view of Fig. 2; Fig. 5 is a transverse section on the line 55, Fig. 3; Fig. 6 is a perspective view of the body member of the clamp; and Fig. 7 is a perspective view of the sliding clampclamped or engaged.

Referring to the drawing, A designates the body member of the clamp, and the same is preferably, although not necessarily, of hollow cylindrical form open at both ends sothat a rope B can be threaded therethrough longitudinally, and on the body is a longitudinal extension 1 that is adapted to re ceive a fastening means, such as a screw 2, that is inserted through an opening 3, and if desired this extension may have a lug or prong 4 extending from its extremity in the direction in which the screw 2 extends, so that by driving this prong into the surface of theobject to which the body element A is to be fastened, a single screw will be sufiicient to hold the body member A firmly in place. The body member A has a longitudinal slot 5 which extends inwardly from the end that has the extension 1, and this slot terminates shortof the opposite end, and it is into this slot that the rope is forced in the final clamping. Cooperating with the body A is an initial clamping member C which is disposed outside the body A and slidable longitudinally thereof, and, as shown in Fig.5, it is curved to conform to the curvature of the body. This clamping element C has a tongue or lug 6 on its concave or hollow side, whichlug is of dove-tailed crosssection and engages in the slot 5 so that the clamping element C can slide on the body. After being once appliedthe slidable clamping element 0 is held in place on the body A by means of a lug or equivalent stop 7 ar ranged on the inner edge of the body. If desired this lug may be an integral part of the body and bent upwardly to the position shown by full lines in Fig. 6, from the dotted line position after the element C is applied. The clamping element O has extending inwardly from one edge a slot 8 that has its length disposed transversely to the slot 5 or circumferentially of the body A, this slot forming two spaced members 9 and 10 between which the end of the rope B is inserted when the element C is in the position shown in Figs. 2 and 4. The slot 8 intersects the slot 5, so that when the rope is in the bottom of the slot 8 it will be in line with the slot 5, and by moving the slide longitudinally of the body A from the position shown in Fig. 41 to that shown in Fig. 3, the

ing element in which the rope is initially rope is tightly clamped. The width of the slots will be somewhat smaller than the connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A rope clamp comprising two relatively slidable members, each member having an open-ended slot, one slot extending in the direction in which the members relatively slide and the other slot extending ;ransversely thereto and adapted to intersect the first-mentioned slot, whereby a rope is inserted successively in the slots and simultaneously clamped in both.

2. A rope clamp comprising a cylindrical body having a longitudinal slot extending inwardly from one end to receive arope, and a member slidable on the body and having an open-ended slot extending transversely to the first-mentioned slot [for initially receiving the rope when the slidable member is in one extreme position, the

rope being engaged in the first-mentioned slot when the member is moved toward its other extreme position.

3. A rope clamp comprising a hollow body having a longitudinally extending slot open at one end, and a member having means engaging in the slot for slidably connecting the member on the body, and said member having an open-ended slot extending transversely to and adapted to intersect the first-mentioned slot.

4. A rope clamp comprising a hollow body having a longitudinally extending slot open at one end, a member having means engaging in the slot for slidably connecting the member on the body, and said member having an open-ended slot extending transversely to and adapted to intersect the firstmentioned slot, and means on the body for forming a stop to limit the movement of the member in a direction to receive the rope to be clamped. i

5. A rope clamp comprising a hollow body open at both ends for permitting a rope to be inserted therethrough, said body having a longitudinally extending slot open at one end, a member on the outside of the body and curved to conform therewith and having an open-ended slot extending trans-- versely to and adapted to intersect the firstmentioned slot, and means for limiting the sliding movement of the said member.

In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.
